摘要:

为进一步研究天名精植物的化学成分及其抗肿瘤活性。本研究采用多种色谱技术(硅胶、RP-C18、Sephadex LH-20以及制备型HPLC等)对天名精石油醚部位的化学成分展开了系统研究,从中分离得到9个萜类化合物。根据理化性质、光谱数据和结合参考文献鉴定化合物为:8-hydroxy-9,10-diisobutyryloxy-thymol(1)、8,10-dihydroxy-9-isobutyryloxy-thymol(2)、9-hydroxy-thymol(3)、10-hydroxy-8,9-dioxy-isopropylidene-thymol(4)、8-hydroxy-9,10-dioxy-isopropylidene-thymol(5)、(3R,6R,7E)-3-hydroxy-4,7-megastigmadien-9-one(6)、blumenol A(7)、4-(3-oxobut-l-enylidene)-3,5,5-trimethylcyclohex-2-en-l-one(8)、loliolide(9)。以上所有化合物均为首次从该种植物分离得到,其中化合物3~8为首次从该属植物分离得到。这些化合物在40 μM浓度下对白血病(HL60)、肺癌(A549)、肝癌(SMMC7721)、乳腺癌(MCF7)以及结肠癌(SW480)五株人肿瘤细胞具有抑制作用。其中,首次报道化合物2对MCF-7和SW480有细胞毒活性,其抑制率分别为72%和81%。

Abstract:

Nine terpenoids were isolated from the petroleum ether extract of Carpesium abrotanoides L. by various column chromatography.Their structures were identified as 8-hydroxy-9,10-diisobutyryloxy-thymol (1),8,10-dihydroxy-9-isobutyryloxy-thymol (2),9-hydroxy-thymol (3),10-hydroxy-8,9-dioxy-isopropylidene-thymol (4),8-hydroxy-9,10-dioxy-isopropylidene-thymol (5),(3R,6R,7E)-3-hydroxy-4,7-megastigmadien-9-one (6),blumenol A (7),4-(3-oxobut-l-enylidene)-3,5,5-trimethylcyclohex-2-en-l-one (8),loliolide (9) by analysis of their NMR and MS data as well as by comparison with the literature.All the above compounds were isolated from C. abrotanoides for the first time,among which 3-8 were identified from this genus for the first time.All isolated compounds exhibited in vitro cytotoxicity against the HL60,A549,SMMC7721,MCF7 and SW480 cell line at the concertration of 40 μM.In addition,compound 2 displayed significant anti-tumor activity MCF-7,SW480,with the inhibitory rates are 72% and 81%,respectively.
